I wanted to get the discount and pay for the whole year, not sure, it wasn't clear weather I actually paid that way or am paying for a month at a time? Need to make that easier to understand and make sure you are paying the way you want for the discount. You can do a follow up survey only if you are on the line when you call -

Good Features but you have to nothing is for free I was so delighted by how easy and intuitive this pdf editor is to use. You upload a word doc you want to convert to pdf or a pdf file that you want to edit. You edit and are very impressed. Until I tried to save. It's browser based but it basically does everything you wish you can do to a pdf file. The interface is very intuitive and can get you going n the first sitting. It will let you edit but you will be unable to save your work until you subscribe. Not another free trial!

On iOS, encrypting your device is as easy as setting a passcode. However, on its own, this encryption does little more than make it easy to remotely wipe a stolen or lost phone. To enable a stronger layer of security, iOS users have to set a passcode on their phone or tablet.
To password protect PDF, open the right document and click File menu. Then choose Set Password in the dropdown.
Run the PDF editor app on iPhone. Tap on the Edit icon in the top right corner of the PDF editor app on iPhone, then select the PDF files you want to combine, finally tap the Merge button at the screen bottom to merge the selected PDF files together into one PDF file on your iOS device.
Run the tool, click on Add files / Add Folder option to insert PDFs & enter the password. Click on the Merge option and hit the Next button. Choose the desired Merge option and select the destination path.
Once the PDF file opens in Documents app, tap on the Menu button (three dots) in the top right corner to bring up menu at the lower section of your iPhone screen. Choose Set Password. Then type in the same password twice. Finally, hit the Set button to confirm and encrypt your PDF file on iPhone or iPad.
Choose Tools > Protect > More Options > Encrypt with Password. Choose File > Protect Using Password, and then choose Advanced Password Protection from More Options.
